FILTER.

SPECIFICATION forming* part of Letters Patent No. 789,942, dated May 16,1905.

Application filed February 18, 1905. Serial No. 246,265.

To all whom, it may concern:

Be it known that I, JOHN E. SKELTON, a citi- Zen of the United States,residing' at Shelbyville, inthe county of Shelby and State of Kentucky,have invented a new and useful Filter, of which the following is aspecification.

This invention relates to filters, and it has special reference to thatclass of filters which are connected with rain-water conduits for thepurpose of filtering the rain-water prior to its passage to the cistern.

The invention has for its object to simplify and improve theconstruction and operation of this class of devices; and with these andother ends in view, which will readily appear as the nature of theinvention is 'better understood, the same consists in the improvedconstruction and novel 4arrangement and combination of parts, which willbe hereinafter fully described, and particularly pointed out in theclaim.

ln the accompanying drawings has been illustrated a simple and preferredform of embodiment of the invention, it being, however, understood thatno limitation is necessarily made to the precise structural detailstherein exhibited, but that the right is reserved to any changes,alterations, and modifications to which recourse may be had within thescope of the invention and without departing from the spirit orsacrificing the efiiciency of the same.

Inv said drawings, Figure 1 is a vertical sectional view showing afilter constructed in accordance with the principles of the invention.Fig. 2 is a horizontal sectional view taken on the line 2 2 in Fig. 1.detail view illustrating a modification.

Corresponding parts in the several figures are indicated throughout bysimilar characters of reference.

The improved filter has been shown as comprising a casing 1 ofcylindrical shape and provided with a detachable cover 2. Said cover hasan inlet 3, adapted to be connected with a water spout or conduit, andthe bottom of the casing has an outlet 4, adapted to be connected withthe outlet leading to the cistern.

The body of the casing has a transverse par- Fig. 3 is a sectional,

tition 5, whereby it is divided into two separate chambers orcompartments 6 and 7. The compartment 6 is provided at the bottomthereof with a waste-pipe 8. The outlet 4 is connected with the bottomof the compartment 7. 4

The casing is provided near its upper end with a diaphragm composed oftwo separate members 9 and 10, which are fitted, respectively, to thecompartments 6 and 7 and which are removably supported upon brackets 11near the upper ends of the walls of said compartments. The compartment 6contains an additional diaphragm 11, detachably supported upon brackets12. The diaphragme 9, 10, and 1l' are constructed of reticulated orforaminous material, such .as perforated sheet metal, wire-gauze, andthe like. The diaphragm member 10 at the upper end of the compartment 7is connected by a bent 'or L- shaped pipe 13 with the lower end of thecompartment 6 beneath a perforated partition 14, which is supported nearthe lower end of said com partrn en t.

A pipe 15 extends through the perforated partition 14 and the diaphragms11 and 9, and said pipe may, if desired, be rigidly connected with thepartition 14, so that the latter may be lifted out thereby.

The partition 5 is provided above the diaphragm composed of the members9 10 with a transverse opening, in 4which is detaehably seated a box ortank 16, one end of which is out away to form an overflow within thecompartment 6. Pivotally supported in said tank is a lever 17, providedat the end which eX- tends within the compartment 7 with a float 18 andconnected at its other end, which extends within the compartment 6, witha stem 19, carrying a valve 20, having a seat 2l at the inner end of thewaste-pipe 8.

The side of the vcasing 1 is provided near its upper end with an opening22, for which a closure 23 is provided. A strainer 24 extends from thelower edge of the opening 22 to the upper edge of the partition 5, andsaid strainer, as will be observed, is disposed beneath the inlet 3,which latter is located at one side of the axis of the casing. rlhecompartment 6 between the partitions 14 and 11 is IOO packed withcharcoal or other suitable filtering material. The compartment 7 betweenthe bottom of the casing and the perforated diaphragm member 10 islikewise packed with filtering material of any suitable description. Thepipe 13, extending through the compart- .ment 7, may be removable, ifdesired. The

tank 16 is provided at or near the overfiow end of said tank and withinthe compartment 6 with a drain-opening 25.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood. y

The water entering at the inlet 3 will pass through t-he strainer 24,where leaves and other trash will be separated, to be subsequentlyremoved through the opening 22. A portion of the water percolatingthrough the strainer 24 will pass into the tank 16, thus raising thefloat 18, depressing the valve-stem 19, and seating the valve 20, thusclosing the wasteoutlet 8. As the water rises to the level of theeut-away end of the tank 16 it overflows land together with a portionof' the water passing through the strainer 24 percolates through thediaphragm member 9, the partitionl 1, and the bottom member 14, as wellas through the filtering material contained between said bottom memberand the partition 11. Finding no outlet through the waste-pipe 8, onaccount of the valve 2O being closed, the water will rise through thepipe 13, overow at the upper end of the latter, and pass through thediaphragm member 10 and percolate through the filtering materialcontained between said member and the bottom of the compartment 7,finally escaping through the exit 4. When the -supply of water throughthe inlet 3 ceases, the contents of the tank 16 will escape through thedrain-opening 25, causing the lioat 18 to descend, thereby unseating thevalve 2O and permitting the water contained in the compartments 6 and 7and .in the pipe 13 to escape through the waste-pipe 8, thus preventingwater from becoming stagnant in the filter-casing in hot weather andpreventing it from freezing during the cold season.

In Fig ofthe drawings has been illustrated a slight modification underwhich the strainer 24 is dispensed with, the inlet-pipe (here designated26) being widened to form a funnel 27 in the wide part of' which astrainer 28 is disposed. The water conduit 29 has been shown as'providedwith a widened or inverted-funnel shaped portion 30, suitably connectedwith the funnel 27. This and other modilications of a like nature may beresorted to within the scope of the invention.

Having thus described the invention, what is claimed is- A filter-casinghaving a transverse partition, filtering-compartments at each side of'said partition, means for conveying water from beneath the filteringdevice in one compartment through the filtering material in the other orrefiltering-compartment to an outlet at the bottom of said refilteringcompartment, a waste-pipe at the bottom of' the space beneath theprimary filter, a pipe extending through the primary filtering device, atank supported detachably in the partition above the filtering devicesin the two compartments, said tank having a cut-away portion above theprimary filter and a small drain-opening, an inlet above said tank, alever fulcrumed in the latter and having a lioat at the end extendingabove the refltering-compartment, a valvestem connected with theopposite end of' said lever and extending through the guide-tube in theprimary filter, and a valve at the lower end of said stem seated in theinner end of the waste-pipe.

In testimony that I claim the foregoing as my own I have hereto aiiixedmy signature in .the presence of two witnesses.
